  Motorcraft™ Ft Oxygen Sensor, Motorcraft™ Upper Oxygen Sensor, Sensor Hego

• Description:

  This genuine Motorcraft heated exhaust gas oxygen sensor is the upstream, front-position unit that installs ahead of the catalytic converter to measure oxygen content in the exhaust stream. The powertrain control module uses its fast-switching signal to trim the air-fuel mixture in real time, keeping combustion near the ideal ratio for power, economy, and low emissions. Motorcraft catalogs it as an upper/front Oxygen Sensor. It fits 2015-2020 Ford vehicles using the 3.5L V6 family, including Explorer and Taurus applications in the front upstream location. When an upstream oxygen sensor ages or becomes contaminated it responds slowly or reads inaccurately, which commonly sets a check engine light with lean, rich, slow-response, or oxygen-sensor circuit codes and leads to poor fuel economy, rough idle, hesitation, and higher tailpipe emissions. Because the upstream sensor directly controls closed-loop fueling, a lazy sensor is a frequent cause of failed emissions testing. Replace with the correct Motorcraft sensor to restore accurate feedback, torque the sensor to specification, and route the wiring away from the hot exhaust. Using the exact Motorcraft unit guarantees the proper connector, heater circuit, and calibrated switching for dependable operation.
